UNITED STATES PATENT OFFICE.

JOHN W. STOOKTON, OF VASHINGTON, DISTRICT OF COLUMBIA.

CHANGEABLE PICTURE. Y

SPECIFICATION forming part of Letters Patent No. 258,261, dated May 23, 1882.

Application tiled March 17, 1882.

.To all whom 'it may concern Be it known that I, JOHN W. S'rocKToN, a citizen of the United States, residing at Washington city, District of Columbia, have invented a new and useful Improvement in Changeable Pictures, of which the following is a specification.

In the accompanying drawings, Figure -1 is a plan view 3 Figs. 2 and 3, detail views of parts of the device.

Similar letters refer to similar parts.

The invention consists in covering a glass or other transparent plate with some opaque substanccsuch as paint, paper, or cloth-of any desired color. Upon this background thus prepared is formed the required picture in outline lby, removing the opaque substance by scraping, cutting, or otherwise, thus leaving an outline transparent picture, whether it be that of a bird, leaf, piece of fruit, or any other object. A second plate of any suitable material, preferably artists board, and madcin a circular form, is placed at the back of the glass plate, having been first covered with `variously-colored paints thrown upon its front surface by means of a brush or otherwise, without regard to method or artistic ei'ect, thus producing a kaleidoscopic and variegated appear-` ance. This second plate is adapted to revolve upon a pin passing through its center. Said pin or bearin g also passes through a boardsuch as is usually placed at the back of framed picv tures, and terminates in a button or other device, which may be used i'or turning the painted plate. This variegated plate, when seen through the transparent parts, already described ofthe front glass, produces a `pleasing and novel effect.

By moving the painted plate it is obvious that the color ot' the object delineated in outline is changed-as, for instance, it' the object be that of a bird its plumage will apparently assume the various colors placed upon said (No model.)

plate. The same effect will be produced if the object be an autumn leaf ora piece of ripe fruit.

It will also be seen that this invention may be variously applied-as, for instance, to the manufaeture'of signs where it is desirable to change the color of the letters.

It is not necessary to make the painted plate in a circular form in every case. It maybe made in the form of a slide running in grooves. The same effect will be produced in either case.

Referring to the drawings, Arepresents the glass plate placed in an ordinary picture-frame; B, the painted plate or disk which revolves at its back, and C the board through which passes the pin or bearing upon which the disk C revolves.

a. represents the object formed by removing the opaque covering, and b notches cut in the edge of the circular plate, by which it may be revolved, a portion of the frame and back being cut away to expose the notches.

c represents the pin or bearing which supports the variegated disk. i

What I claim, and desire to secure by Letters Patent of the United States, is

1. The method of changing the color or hue of outline transparent pictures by means of a revolving or sliding variegated disk at the back of a coated plate ot' glass or other transparency, the picture bein gformed by removing portions of said coating, substantially as described.

2. The combination of the plate A, provided with the outline pictures a, and the variegated plate or disk B, substantially as set forth.

3. The combination of the plateA, provided with the outline pictures a, the variegated plate or disk lB, and the pin or bearing c, attached to the back (l, substantially as specified.
